Hi all,
I have a spur coming down vertically from under the first floor (floor) into the kitchen that feeds two rads and then loops back up into the ceiling.
I have tested that all rads get hot when I turn these two off.
I am removing both rads, moving the spur piping so It's less obtrusive and fitting a new single rad in place. I am going to drain the system, cut the spurs so I can remove both rads and fix up/decorate the wall behind.
I am going to do this before I have a new boiler fitted in a couple of weeks and the new rad will go in at the same time - engineer is doing the plumbing to put the rad back in.
I need a temporary blank on the spur so I can re-fill and use the heating for a couple of weeks until the replacement. I was going to use blank ends, but thinking about it, will I be creating air locks in the pipework if I simply have essentially two long blanked off tails coming down vertically (about 2.6 metres), or will the air be able to sort itself out?
I was considering using some plastic pipe to loop from the down pipe into the up pipe (instead of just blanking off both ends) of the spur so there is a flow to reduce any air pockets, but this might make it worse?
Would it be sensible to use a loop instead of just blanking the ends, and if there was an air pocket, does it really matter as it will all be drained and re-fitted in a few weeks anyways?
Sorry for the long winded description - trying to give as much info as possible!
